The Biblical Hebrew form of Hannah, meaning “grace” or “favor.” Hopefully little Chana will do her parents a favor and be a good sleeper. Or at least eat her veggies.
There aren't really any suitable nicknames for Chana.
Famous people named Chana:
Actress Chana Eden; poet Chana Bloch; author Sarah Chana Radcliffe; sculptor Chana Orloff.
To pronounce this name accurately, the "Ch" sound should be a guttural sound from the throat. But since that isn't a familiar sound to the English language, Chana is often pronounced SHAY-na.
